Here's a look inside the Ford Ecoboost 1.6L Turbocharged engine and how it works!
The Ford Ecoboost is a 4 cylinder engine, with the 1.6L variant preceding the modern 1.5L 3 cylinder unit. It has dual variable valve timing that is driven by a dry timing belt. Some Ecoboost engines were driven by a wet belt system which often failed.
This engine features direct injection, which means it can make more power with better fuel efficiency and less emissions, at the cost of serviceability and reliability. Carbon buildup is a common issue as a result of direct injection and a poorly designed PCV system.
The main issue with these engines is they overheat due to a head-gasket design fault. There exists a small coolant channel between the cylinders to aid with cooling, as these little engines are forced to create a lot more power than they should be able to handle.This channel creates a weak point in the head-gasket, causing coolant to enter the combustion chamber and vice versa. Coolant mixes with oil, and as a result the engine fails catastrophically if the problem isn't identified early enough.
In this video we take apart the 1.6T engine from a 2013 Ford Escape that had an overheating condition.
